gas lift pump

A gas lift pump is a device used to bring oil from a well to the surface. It works by introducing compressed gas into the liquid near the bottom of the well. This mixture of gas and liquid becomes less dense and more buoyant than the liquid alone, allowing the reservoir's natural pressure to push it upwards and out of the well. Gas lift systems have the advantage of having no moving parts and can handle liquids containing solid particles. While once widely used for pumping water, brine, and oil, they are now less common than other artificial lift methods.123
